Yes, once live. I flopped a J high straight flush playing 87h. Got it all in on the flop against a guy with AT (ace of hearts obviously). Turn Qh, River Kh. I played the K-high st. fl. board and the guy got not only the pot but the casino's bonus for hitting the royal. That's my worst bad beat, not only in cards value (I guess they can't get worse than K-high st. fl.), but also odds on villains draw after the money went in. Wasn't a huge pot though - only 1/2NL and I don't think the vllain had quite a full stack.

I ended up second; Rok ended up winning (the guy who caught the royal) - he ran hot after that and ended up with a 5-1-1 chiplead three handed, I managed to hold on for second, stage a minor comeback then lose a race to end it. Only a $10 buyin anyway, so it was only like 300 for the win anyway and 200 or so for second.

Lots of talk in the chatbox after the hand though.

...now if only I still played on UB, played cash games, loved extra rake and happened to be playing a cash game there when this hand happened...

Oh well. Not many players can say they have lost with a king high straight flush.

It's a standard hi versus low str. flush (as if that could ever be considered "standard"). The rank of the hands is what makes it seem so spectacular. It would have been nice to see this hand played out a bit, and then the crushing defeat...lol.

Like you said, you can now say you lost with this hand. If someone asks what hand beat you then stack them immediately.
